Claims.

This invention relates generally to devices used in the permanent waving of human hair, and more particularly it is concerned with the construction of devices used to supply heat, for the steaming operation.

In the permanent waving of hair it has become relatively common to use so-called heaters, which are clipped over the wound hair, for the steaming operation. Of more recent years socalled pre-heating equipment has come into usage, that is, equipment of the kind disclosed and claimed in Patent No. 1,972,186, granted September 4, 1934. Such equipment makes use of a so-called pre-heating apparatus, together with heat storage devices which are heated up to a predetermined temperature and then applied to the wound hair.

In the operation of pre-heating equipment I have found that there is a serious tendency for the handles of the heat storage devices to be heated to relatively high temperatures. Frequently the temperatures reached are such as to make the devices unsafe to be handled by an operator. In this connection it should be noted that frequently the heat storage devices are permitted to remain clipped upon the pre-heater for considerable periods of time, during which the handles are heated not only by conduction, but also by convection currents of air. Even though the temperature attained by the handles may not be such as to burn the skin, any unpleasant temperature increases the possibility of accidental burning of the subject. Another difficulty which has been experienced has been the attainment of a proper heat storage capacity, in the heat storage devices, without making the devices bulky in size.

It is an object of the invention to provide a heat storage device having improved finger gripping surfaces which will not be heated to unsafe or unpleasant temperatures.

A further object of the invention is to provide a heat storage device capable of adequate heat storage capacity, without being bulky in size.

Further objects of the invention will appear from the following description in which the preferred embodiment of the invention has been set forth in detail in conjunction with the accompanying drawing.

Referring to the drawing:

Fig. 1 is a side elevational view, illustrating a heat storage device in accordance with the present invention, applied to a protector and curler assembly.

Fig. 2 is a view showing the same device as in Fig. 1, but looking towards the end of the device.

Fig. 3 is a bottom plane view of the heat storage device. 7

Fig. 4 is a cross-sectional detail taken along the line- 4-4- of Fig. 1, on an enlarged scale.

Fig. 5 is a cross-sectional view taken along the line 5-5"of FigI =4, and on the same enlarged scale. I

The device as illustrated in the drawing consists generally of a pair of duplicate heat storage elements l0, which are attached to a mounting ll, whereby the elements can be moved toward or away from each other. Also attached to the mounting H are the handles l2, which carry the finger grip pads l3 The elements ID are made of some suitable metal or metal alloy, which will afford a fairly high specific heat without being unduly heavy, as for example an aluminum or magnesium alloy. The inner opposed faces l4 are concave, while the outer faces are generally convex.

The mounting 'll :consists of a pair of yokelike arms 16, which are pivotally connected by pin IT. A spring l8 serves to urge together the elements [0, with sufficient force to retain the device upon a curler or upon the heating element of pre-heated apparatus. The branches or portions l6a of each arm I6, are shown attached to the associated heat storage element by means of rivets l9. The space directly between arm portion Him, is occupied by a bulge 2|, whereby the heat storage capacity is increased, without materially increasing the lateral dimensioning of the device.

The handles l2 are formed of suitable molded insulating material, such as Bakelite, or some equally effective synthetic resin product. The handles are attachted to the arms [6 by suitable means such as rivets 22.

The pads l3 are preferably formed of resilient vulcanized rubber, with a cloth or felt surfacing 23 formed as an integral part of the same. In order to attach these pads to the handles, each pad is shown provided with a pair of integral studs 24, with the ends of these studs being provided with enlarged heads 26. The handle in turn is provided with openings 21, through which the studs 24 can be forced, to provide an adequate and convenient attachment.

In general my device is utilized in the same manner as the heat storage devices disclosed in the above-mentioned Patent No. 1,972,186. In Figs. 1 and 2 the device is shown clipped upon the curler of a protector curler assembly 20, for a steaming operation. The bulge construction of the heat storage elements In provides a maximum of heat storage capacity, without unduly increasing the lateral dimensioning of the device. The handles l2 of insulating material are relatively poor conductors of heat, and in practice these handles will not conduct sufficient heat to the pads l3 to occasion disintegration of the VulcaniZed rubber. The rubber pads l3 are likewise relatively poor conductors of heat, so that as a net result, the surfaces 23 can at all times be necting said members together, a pair of handles of molded insulating material secured to said mounting whereby said elements can be swung apart by pressing said handles together, and pads of resilient vulcanized rubber secured to said handles and forming finger-gripping surfaces, the outer faces of said pads having a covering of felt.

2. A device for the permanent waving of hair, comprising a pair of opposed elements adapted to apply heat to wound hair, a mounting for hingedly connecting said elements together, a pair of handles formed of molded insulating material, said handles being secured to said mounting whereby said elements can be swung apart by pressing said handles together, pads of resilient vulcanized rubber secured to said handles and forming finger-gripping surfaces, said pads being retained upon said handles by studs formed integral with said pads and extending through openings formed in said handles.

3. A device for the permanent waving of hair,

comprising a pair of opposed elements adapted to apply heat to wound hair, a mounting for hingedly connecting said elements together, a pair of handles formed of molded insulating material secured to said mounting, whereby said elements can be forced apart by pressing said handles together, and pads of resilient vulcanized rubber secured to said handles and forming finger-gripping surfaces, said pads being retained to said handles by studs formed integral with the pads and extending through openings formed in the handles, the outer faces of said pads having a surfacing of felt.

4. A heat storage device for the permanent waving of hair, comprising a pair of elongated heat storage elements, the opposed inner faces of said elements being concave, a mounting serving to hingedly connect said elements together, said mounting including a pair of arms with each arm having two points of attachment to its associated heat storage element, the points of attachment being near the ends of the element and on the outer side of the same, each of said elements being formed of a solid mass of metal with more of the metal being distributed in the medial region of each element, than at the ends thereof.

5. A heat storage device for the permanent waving of hair, comprising a pair of elongated heat storage elements, a mounting for hingedly connecting-said elements together whereby said elements are retained in parallel relationship, the inner faces of said elements being concave to enable application to wound hair, said mounting including a pair of yoke-like arms, the two branches of each arm having points of connection to an associated heat storage element at points near the ends of the element, said elements being formed of a mass of metal in which heat can be stored, the outer side of each of said elements being bulged outwardly in a region between the two points of connection, thereby affording added heat storage capacity.
